HV Cables on DCs: Sense-A2, Guard-A3 and Field-A4

HV cables on scintillators: Front && rear PMTs-A8. Hv settings 1150 Volts(works). In counting room front-A1(BNC) and rear-A2(BNC).

Plan: A3 should be gate. A4 - Start for TDC. A12-trigger.

HV Settings on drift chambers S:F:G=1400:-700:980


Setup TIming

Accelerator sends the Gun gate to HRRL counting room on channel BM

The accelerator Gun gate starts our Stanford pulse generator.

The Stanford pulse generator outputs 2 pulses
one pulse is for the ADC gate and G1 trigger for V1495
The second pulse create a trigger for the DAQ

Singles scaler counts
